DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention. These are merely examples of apparatuses and methods consistent with one aspect of the present invention described in the appended claims.

FIG. 1 is a schematic diagram of an operation environment of a group management method according to some exemplary embodiments. As shown in FIG. 1, the operation environment includes a client 110 and a server 120. FIG.

The client 110 may be a client running on the terminal and provided by any instant messaging service provider.

The server 120 is a server provided by an instant messaging service provider of the client 110 and can communicate with the client 110 via a wired or wireless network.

FIG. 2 is a flowchart of a group creating method according to an exemplary embodiment. As shown in FIG. 2, the group creating method is applied to the server 120 in the execution environment shown in FIG. 1, Includes the following steps.

In step 201, a request to create a target subgroup is received.

Here, the create request includes the group identifier of the target group to which the client that has sent the create request belongs.

In step 202, a target subgroup associated with the target group is created.

Here, the members of the target subgroup are a subset of the members of the target group.

In step 203, the subgroup identifier of the target subgroup is transmitted to the member of the target subgroup.

In summary, according to the group creating method according to the present embodiment, when a request for creating a target subgroup is received containing a group identifier of a target group to which a client that has sent a create request belongs, And transmits the subgroup identifier of the target subgroup to the member of the target subgroup. Here, the members of the target subgroup are a subset of the members of the target group. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, Safety can be guaranteed.

FIG. 3 is a flowchart of a group creating method according to an exemplary embodiment. As shown in FIG. 3, the group creating method is applied to the client 110 in the execution environment shown in FIG. 1, Includes the following steps.

In step 301, a request to create a target subgroup is sent to the server.

Here, the creation request includes the group identifier of the target group.

In step 302, the subgroup identifier of the target subgroup transmitted from the server is received.

Here, the target subgroup is a subgroup associated with the target group to which the client belongs, and the members of the target subgroup are a subset of the members of the target group.

According to the group creating method according to the present embodiment, a request for creating a target subgroup is transmitted to the server. After the server receives the request for creation, the target subgroup is created, And the client can successfully create the target subgroup when receiving the subgroup identifier. Here, the target subgroup is a subgroup associated with the target group to which the client belongs, and the members of the target subgroup are a subset of the members of the target group. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, Safety can be guaranteed.

4A is a flowchart of a group creation method according to an exemplary embodiment. As shown in FIG. 4A, the group creating method is applied to the execution environment shown in FIG. 1, and the group creating method includes the following steps.

In step 401, the client sends a creation request to the server to create the target subgroup.

When a user uses the group function, the user often needs to communicate with only a part of the users of the group. In this case, the user sends a request for creating a target subgroup to the server through the client . Here, the create request includes the group identifier of the target group to which the client that sent the create request belongs.

For example, referring to FIG. 4B, when the user needs to create one subgroup in the target group "XX group", the user selects "Create subgroup" in the group message interface of the "XX group" Select an item. After receiving the selection signal, the client displays an interface for inquiring the confirmation of creation, and sends a creation request for creating the subgroup to the server when confirmation is selected by the user. In actual implementation, the user clicks the group name of the target group in the display interface containing the group name of each group displayed on the client, selects the subgroup creation from the selection menu displayed after clicking, May be requested to create a target subgroup through a method of selecting " OK " The schematic diagram can be referred to FIG. 4C, and the present embodiment is not limited to this.

In step 402, the server receives a create request to create a target subgroup sent from the client.

In step 403, the server creates a target subgroup associated with the target group.

After receiving the create request, the server may create a target subgroup associated with the target group. The members of the target subgroup are a subset of the members of the target group. In actual implementation, in order to identify the identity of the target subgroup created by the server, the server creates a target subgroup and at the same time generates a subgroup identifier of the target subgroup, and this embodiment does not further describe this.

Further, in order to identify the creator of the target subgroup, the creation request may further include a client. In addition, since the client can invite other group members of the target group to subscribe to the target subgroup when requesting the creation of the target subgroup, the creation request transmitted from the client may further include other clients invited by the client . That is, the creation request may include a list of members of the target subgroup. For example, when the client receives the selection signal for creating the subgroup, it displays the interface of inquiry as shown in FIG. 4E, and the inquiry interface includes the list of members of the target group. When the user selects another group member to invite from the list of members of the target group and clicks OK, the client sends a create request to the server, which includes the group identifier, the client and any other clients invited. Thus, when the server receives the create request, it can create a target subgroup corresponding to the member list.

In actual implementation, to protect the privacy of other group members, the server first sends invitation information to other clients inviting other group members to join the target subgroup, and after the other client accepts the invitation and feeds back the confirmation information The target subgroup corresponding to the member list may be created, but the present embodiment is not limited thereto.

In step 404, the server sends the subgroup identifier of the target subgroup to the members of the target subgroup.

After creating the target subgroup, the server may send the subgroup identifier of the target subgroup to the members of the target subgroup to inform the members of the target subgroup of the success of creation of the target subgroup.

In step 405, the member of the target subgroup receives the subgroup identifier of the target subgroup transmitted from the server.

A member of the target subgroup may receive the subgroup identifier of the target subgroup transmitted from the server. In addition, the client may store the received subgroup identifier after receiving the subgroup identifier of the target subgroup. For example, referring to FIG. 4D, the client stores the received subgroup identifier " XY " in the target group.

It is to be understood that the present embodiment is not limited to the number of subgroups that can be created in the target group, and that the clients that create each subgroup may be the same or different clients, and the present embodiment is not limited thereto.

According to the group creating method according to the present embodiment, when receiving a creation request including a group identifier of a target group to which a client that has sent a creation request as a creation request for creating a target subgroup belongs, Creates a target subgroup associated with the group, and transmits the subgroup identifier of the target subgroup to the member of the target subgroup. Here, the members of the target subgroup are a subset of the target group members. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, We can guarantee safety

However, in actual implementation, the client first creates one sub-group, and then creates a sub-group of the target group, Other clients may be invited to subscribe to the target subgroup. Referring to FIG. 4F, the following steps may be further performed.

In step 406, the client sends a subscription request to the server to subscribe the other clients of the target group to the target subgroup.

After the client succeeds in creating the target subgroup, the client may invite other clients of the target group to join the target subgroup. Thus, at this point, the client sends a subscription request to the server requesting to join the other clients of the target group to the target subgroup.

In step 407, the server receives a join request to join the other clients of the target group to the target subgroup.

In step 408, the server adds the other client to the target subgroup and marks the client as the creator of the target subgroup.

After receiving the subscription request, the server adds other clients to the target subgroup and marks the client as the creator of the target subgroup.

In actual implementation, in order to protect the privacy of other clients, the server first sends invitation information to invite other clients to subscribe to the target subgroup, receives invitations from other clients, May be added to the target subgroup, and the present embodiment is not limited thereto.

It should also be understood that any member of the target subgroup may initiate group communication after the server has created the target subgroup. Referring to FIG. 4G, the step of initiating the group communication by the members of the target subgroup includes the following steps.

In step 409, the server receives the communication information transmitted from the member of the target subgroup.

When any member of the target subgroup starts group chatting, it may send communication information to the server and the corresponding server may receive the communication information sent from the member. Here, the communication information includes the subgroup identifier of the target subgroup. In actual implementation, the information content may be further included in the communication information. For example, referring to FIG. 4H, the present embodiment illustrates a case where the member is a client that has created a target sub group. When the user intends to start group chatting in the " XY subgroup " XY subgroup "and enter" XY project is completed well ". Everyone, thank you. "After inputting the information of the content, click Send. When the client using the member receives a click signal, he / she has completed the "XY Project. And "XY subgroup" to the server.

In order to identify the transmitting side of the communication information, the communication information may further include an identity identifier of the member that has transmitted the communication information, and the present embodiment is not limited to the information content of the communication information.

In step 410, the server searches the list of members of the corresponding target subgroup based on the subgroup identifier of the target subgroup.

After receiving the communication information, the server searches the list of members of the target subgroup corresponding to the subgroup identifier in the communication information, for performing the subsequent steps.

In step 411, the server transmits the communication information to other members other than the transmitting side of the communication information among the member list of the target subgroup.

After retrieving the list of members of the target subgroup, the server may transmit communication information to other members of the list of members of the target subgroup other than the sender of the communication information.

In step 412, the other member receives the communication information transmitted from the server.

The other member may receive the communication information transmitted from the server and display the information content in the communication information in the subgroup corresponding to the subgroup identifier after receiving the communication information. If the identity of the member that transmitted the communication information is included in the communication information, the other client displays the information content and also displays the identity of the transmitting party, and this embodiment will not be described further.

It should also be appreciated that the create request sent by the client may employ the same message body format as the group message of the target group. For example, if the message body of a group message includes a sender identifier, a group identifier, a timestamp, and message content, then the create request includes message identifiers, a group identifier, a timestamp, . Also, the display form of the creation request can be represented by adopting the same display format as the group message. For example, if the group message is XML (eXtensible Markup Language) format, the creation request is also XML format, and if the group message is JavaScript Object Notation (JSON) format, the creation request is also JSON format, , Then the request to create is also binary format.

5 is a flowchart of a group withdrawal method in accordance with an exemplary embodiment. As shown in FIG. 5, the group withdrawal method is applied to the server 120 of the execution environment shown in FIG. 1, and the group withdrawal method includes the following steps.

In step 501, a withdrawal request to withdraw from the target subgroup is received.

Here, the withdrawal request includes the subgroup identifier of the target subgroup. The target subgroup is a subgroup associated with one target group and the members of the target subgroup are a subset of the members of the target group.

In step 502, based on the subgroup identifier of the target subgroup, a list of members of the corresponding target subgroup is retrieved.

In step 503, the client that has transmitted the withdrawal request is deleted from the list of members of the target subgroup.

According to the group withdrawal method according to the present embodiment, after receiving a withdrawal request for withdrawing from the target subgroup and receiving a withdrawal request, a list of members of the target subgroup corresponding to the subgroup identifier of the target subgroup And deletes the client that has transmitted the withdrawal request from the member list of the target subgroup. Here, the withdrawal request includes the subgroup identifier of the target subgroup, the target subgroup is a subgroup associated with one target group, and the member of the target subgroup is a subset of the members of the target group. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, Safety can be guaranteed.

The subgroup members of the target subgroup may request withdrawal so that the server uses the resources to deliver the communication information to the member but avoids the situation where the communication information is of no value to the member, You can save even more. Further, the communication information can avoid interference with the member, and the user experience can be improved.

6 is a flowchart of a group withdrawal method according to one exemplary embodiment. As shown in FIG. 6, the group withdrawal method is applied to the execution environment shown in FIG. 1, and the group withdrawal method includes the following steps.

In step 601, the client sends a withdrawal request to the server to withdraw from the target subgroup.

When an arbitrary user of the target subgroup desires to withdraw, it can transmit a withdrawal request to withdraw from the target subgroup to the server through the client used by the user. Here, the withdrawal request includes the subgroup identifier of the target subgroup. The target subgroup is a subgroup associated with one target group and the members of the target subgroup are a subset of the members of the target group.

In step 602, the server receives a withdrawal request to withdraw from the target subgroup.

Thus, the server can receive the withdrawal request sent from the client.

In step 603, the server retrieves a list of members of the corresponding target subgroup based on the subgroup identifier of the target subgroup.

In step 604, the server determines whether the client that sent the withdrawal request is the creator of the target subgroup.

After receiving the withdrawal request, the server may determine whether the client that sent the withdrawal request is the creator of the target subgroup for the subsequent steps. In actual implementation, in order to identify which client in the target subgroup has requested withdrawal, the withdrawal request may include the identity identifier of the client that sent the withdrawal request. Thus, the server can determine whether the identity identifier of the client that sent the cancellation request is the identity of the creator of the target subgroup in the list of members of the target subgroup. As a result of the determination, in the case of the identity identifier of the creator of the target subgroup, the server can know that the client is the creator of the target subgroup. As a result of the determination, if the target subgroup is not the creator, the server can know that the client is not the creator of the target subgroup.

In step 605, if the client that sent the withdrawal request is not the creator of the target subgroup, the server performs the step of deleting the client that sent the withdrawal request from the list of members of the target subgroup.

As a result of the determination, if the client that transmitted the cancellation request is not the creator of the target subgroup, it is described that the client is a general user of the target subgroup. At this time, the server directly deletes the client from the member list of the target subgroup .

On the other hand, if it is determined by the server that the client that sent the withdrawal request is the creator of the target subgroup, when the group owner withdraws from the group similar to the conventional group, the group is directly disbanded. Therefore, at this time, the server directly disposes the target subgroup and terminates the processing.

In step 606, the server transmits withdrawal success information to the client that has transmitted the withdrawal request.

After performing the delete operation, the server can transmit the unsubscription success information to the client that has transmitted the unsubscription request, in order to notify the client that has transmitted the unsubscription request of unsuccessful unsubscription from the target subgroup.

In step 607, the client that has transmitted the withdrawal request receives the withdrawal success information transmitted from the server.

Accordingly, the client that has transmitted the withdrawal request can receive the withdrawal success information transmitted from the server, and upon receipt of the withdrawal success information, it can be found that the withdrawal succeeds from the target subgroup. Here, the unsuccessful unsubscription information is information after the server receives the unsubscription request, and then deletes the client that has sent the unsubsquest from the member list of the target subgroup and then returns it.

According to the group withdrawal method according to the present embodiment, after receiving a withdrawal request for withdrawing from the target subgroup and receiving a withdrawal request, a list of members of the target subgroup corresponding to the subgroup identifier of the target subgroup And deletes the client that has transmitted the withdrawal request from the member list of the target subgroup. Here, the withdrawal request includes the subgroup identifier of the target subgroup. The target subgroup is a subgroup associated with one target group and the members of the target subgroup are a subset of the members of the target group. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, Safety can be guaranteed.

The subgroup members of the target subgroup may request withdrawal so that the server uses the resources to deliver the communication information to the member but avoids the situation where the communication information is of no value to the member, You can save even more. Further, the communication information can avoid interference with the member, and the user experience can be improved

7 is a flowchart of a group withdrawal method according to an exemplary embodiment. As shown in FIG. 7, the group withdrawal method is applied to the server 120 of the execution environment shown in FIG. 1, and the group withdrawal method includes the following steps.

In step 701, a request to withdraw from the target group is received.

Here, the withdrawal request includes the group identifier of the target group.

In step 702, the subgroup identifier associated with the group identifier is inquired.

Here, the member of the subgroup corresponding to the subgroup identifier obtained by inquiry is a subset of the members of the target group.

In step 703, a list of members of the target group corresponding to the group identifier is retrieved.

In step 704, the client that has transmitted the withdrawal request is deleted from the list of members of the target group.

In step 705, a member list of the corresponding subgroup is searched based on the subgroup identifier obtained by inquiry.

In step 706, the client is deleted from the member list of the sub group obtained by searching.

According to the group withdrawal method according to the present embodiment, upon receiving a withdrawal request to withdraw from the target group, the subgroup identifier related to the group identifier of the target group is inquired, and based on the group identifier, Searches the member list of the corresponding subgroup based on the subgroup identifier obtained by inquiry, deletes the client that has transmitted the withdrawal request from the member list of the target group, searches the member list of the corresponding subgroup based on the inquiry, Delete the client from the member list. Here, the member of the subgroup corresponding to the subgroup identifier obtained by inquiry is a subset of the members of the target group. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, Safety can be guaranteed.

In addition, since the client leaves the target group and leaves the target group at the same time, the server does not need to continuously transmit communication information of the subgroup to the client. Accordingly, in the related art, it is possible to solve the problem that the server continuously transmits the communication information of the subgroup of the target group to the client and wastes server resources, saves server resources, and allows the server The communication information of the subgroup of the target group is not transmitted, so that the leakage of the communication information of the subgroup can be prevented and the safety of the communication information of the subgroup can be assured.

8 is a flowchart of a group withdrawal method according to an exemplary embodiment. As shown in Fig. 8, the group withdrawal method is applied to the execution environment shown in Fig. 1, and the group withdrawal method includes the following steps.

In step 801, the client sends a withdrawal request to the server to withdraw from the target group.

When an arbitrary user of the target group desires to withdraw, the withdrawal request for withdrawing from the target group can be transmitted to the server through the client used by the target group. Here, the withdrawal request includes the group identifier of the target group.

In step 802, the server receives a withdrawal request to withdraw from the target group sent from the client.

In step 803, the server queries the subgroup identifier associated with the group identifier.

After receiving the withdrawal request, the server may inquire the subgroup identifier associated with the group identifier for subsequent steps. According to the method of generating the subgroup identifier, when the subgroup identifier is related to the group identifier, it is known that the subgroup corresponding to the subgroup identifier is a subgroup of the target group. Therefore, the member of the subgroup corresponding to the subgroup identifier obtained by the inquiry is a subset of the target group member.

In step 804, the server retrieves a list of members of the corresponding target group based on the group identifier.

The server may retrieve the list of members of the target group corresponding to the group identifier included in the withdrawal request for the subsequent step after receiving the withdrawal request.

However, in actual implementation, the server may perform steps 803 and 804 at the same time. Alternatively, the server may perform step 803 and then perform step 803 And it should be understood that the present embodiment is not limited to the actual execution order.

In step 805, the server determines whether the client that sent the withdrawal request is the creator of the target group.

The server may determine whether the client that has transmitted the withdrawal request is the creator of the target group for performing the subsequent steps after receiving the withdrawal request. In actual implementation, it may include the identity of the client who has sent the withdrawal request to the withdrawal request, in order to identify which client of the target group has requested withdrawal. The server can determine whether the identity identifier of the client that sent the withdrawal request is the identity identifier of the target group creator in the list of members of the target group. As a result of the determination, in the case of the identity identifier of the creator of the target group, the server can know that the client that sent the withdrawal request is the creator of the target group. As a result of the determination, if the ID is not the identity of the creator of the target group, the server can know that the client that sent the withdrawal request is not the creator of the target group.

In step 806, if the client that sent the withdrawal request is not the creator of the target group, the server performs the step of deleting the client that sent the withdrawal request from the list of members of the target group.

As a result of the server determination, if the client that transmitted the cancellation request is not the creator of the target group, the client that transmitted the cancellation request is a general user of the target group. At this time, Can be deleted.

On the other hand, if it is determined by the server that the client that sent the withdrawal request is the creator of the target group, the group is directly disassociated when the group owner leaves the group, similar to the conventional group. Thus, at this time, the server dissolves the target group. Also, since the target subgroup is related to the target group, the subgroup of the target group also becomes non-existent after the target group is disbanded, and the server may disassociate the subgroup associated with the target group simultaneously with the dissolution of the target group. Then, the processing is terminated.

In step 807, the server determines whether or not the client that transmitted the withdrawal request is the creator of the subgroup corresponding to the subgroup identifier, with respect to each subgroup identifier in the subgroup identifiers obtained by inquiry.

In actual implementation, the server may determine whether the identity identifier of the client that sent the unsubscribe request is the identity of the creator of the subgroup corresponding to the subgroup identifier. As a result of the determination, if it is the identity identifier of the creator of the subgroup corresponding to the subgroup identifier, the server can know that the client that transmitted the withdrawal request is the creator of the subgroup corresponding to the subgroup identifier. As a result of the determination, if it is not the identity identifier of the creator of the subgroup corresponding to the subgroup identifier, the server can know that the client that sent the withdrawal request is not the creator of the subgroup corresponding to the subgroup identifier.

It should be noted that since the target group may include a plurality of subgroups and some subgroups include the client that sent the withdrawal request but not some subgroups, It is determined whether or not the identity of the client is included in the member list of the subgroup corresponding to the subgroup identifier for each subgroup identifier. As a result of the determination, if the client's identity identifier is included, it is determined whether or not the client is the creator of the subgroup corresponding to the subgroup identifier. The present embodiment will not be described in detail hereafter.

In step 808, if the client that transmitted the withdrawal request is not the creator of the subgroup corresponding to the subgroup identifier, the server performs the step of deleting the client from the member list of the subgroup corresponding to the subgroup identifier.

As a result of the determination by the server, if the client that transmitted the withdrawal request is not the creator of the subgroup corresponding to the subgroup identifier, the client directly exits from the subgroup similarly to the conventional group, Delete the client from the member list of the subgroup.

On the other hand, if it is determined by the server that the client that sent the withdrawal request is the creator of the subgroup corresponding to the subgroup identifier, the client is the group owner of the subgroup. At this time, when the group owner leaves the group similar to the conventional group, the group is directly disassociated, and the server disassociates the group.

In step 809, the server transmits withdrawal success information to the client that has transmitted the withdrawal request.

After performing the deletion operation, the server transmits withdrawal success information to the client in order to notify the client that has transmitted the withdrawal request of unsuccessful withdrawal from the target group and the target group. Herein, the withdrawal success information indicates that the withdrawal succeeds from the target group and the target group and from the subgroup including the client.

In step 810, the client that has transmitted the withdrawal request receives the withdrawal success information returned from the server.

Accordingly, the client can receive the withdrawal success information returned from the server, and upon receipt of the withdrawal success information, the client has already succeeded in withdrawing from the target group and the target group, and thereafter, Prevents the client from interfering with the communication information of the target group's subgroup continuously after leaving the target group, because it no longer receives the communication information of the target group's subgroup, thereby improving the supervision of the user.

According to the group withdrawal method according to the present embodiment, upon receiving a withdrawal request to withdraw from the target group, the subgroup identifier associated with the group identifier of the target group is inquired, and based on the group identifier, Searches the member list of the group, deletes the client that has transmitted the withdrawal request from the member list of the target group, searches the member list of the corresponding subgroup based on the obtained subgroup identifier, &Lt; / RTI > Here, the member of the subgroup corresponding to the subgroup identifier obtained by inquiry is a subset of the members of the target group. Therefore, it is possible that other members not belonging to the target group are included in the newly created group, that is, the server needs to transmit the communication information of the newly created group to the other members, thereby solving the problem of the related art that wastes server resources, It is possible to save server resources and to prevent leakage of communication information of a newly created group because the server does not transmit communication information of a newly created group to other members not belonging to the target group, Safety can be guaranteed.

The present embodiment detects whether or not the client is the creator of the target group before deleting the client in the list of members of the target group, performs the deletion operation only when the client is not the creator of the target group, In the case of the creator of the target group, the target group and the target group's subgroup are dissociated. Therefore, it is possible to prevent the server from continuing to transmit communication information to the subgroup and waste server resources. Similarly, before deleting the identity identifier in the member list of the subgroup corresponding to the subgroup identifier, the client first detects whether the client is the creator of the subgroup, and performs the delete operation only when the client is not the creator of the subgroup And when the client is the creator of the subgroup, directly divides the subgroup. Therefore, it is possible to prevent the server from continuing to transmit communication information to the subgroup and waste server resources.
